` The body portion 1'at the point of joinder thereof with the` extension 18 `and e at itsV transverse center, is provided with acountersunkopening 2liI and a dependingboss 25 f which registersevvith the opening 24. Securedto the body portion 1 and depend' thrcugh the cpenngzaa is a pivot a@ 135i posato bepresently'referred 'tot 'tired th.

nipper of Ati ing portion `o f the plate 17,35 well as joeing coextensive therewith, is a scale carrying member 27. Y Y v Y Y The device includes .an adjutabl bined saw guide and carrier which is of inverted yoke shape and formed of two/sections28 and 29. The setionw29 -at `itsrear Ais formed with an vextension '30"and" alug 31, Vthe former being arranged above the latter and projeetingrearwardly therefrom;

`The section 29 is of ymaterially lgreater lengthk than the section `and Uprojects rea-rwardly",` f'r'om` the latter. The Vsections 28 and 29'at, their forward ends are fiush with each otherl andthe section 28 `is detachably connected to the section 29,' a plurality of hold fast devices 3,2.

The upperpart of the inner faces/of the lsections 28, 29 areprovided with ygrooves y33,34' respectively whichopp'ose each other and in which'is 'adapted toisli'dea reinforce;r mentat the top of the saw blade/36, and

l such 'reinforcement' maybe an. extension tions or a scale` and is Vadjnstably con-v nected to lthecombined saw vguide and ear@ rier by a set screw 38'.; j

Associated with the combined saw guide and Carrier is a coupling mechanism 'for Connecting ,it toa means Afor adjustingthe combined saw guide 4and carrier in a vertical inclined plane andthe said meansis indicated generallyby the reference character 4l. The coupling mechanism includes a pair oflsuperposed links 42,43; the former is pivotally connected as 44 to 'the adjusting means 41 and also jiiv'otallyv connected" as at to the extension 30. The link `43 is pivo'tally connected asl at 46 tothe adjusting means 41 and [also Yp ivota'lly connectedk as vat 47 tothe lug 31. The construction and -arirangement of the coupling .mechanism per mits of 'the' links 42'and v43 Itobe lswung on the pivots 44and'46 to a vertical position carrying vthe combinedl saw VIguide and carrier therewith whereby` the latter can be held -in'ieleva'ted position and'suspended fat Vright angles with respect t-"o the said ymeans 42. The Ycombined guide Iand carrier can also be swung on the pivots 45 and'47.` I

-The means y41 for `std jiisti-rig the combined saw guide yand carrier to a vertical inclined plane comprises va pivot-ed vpoint-er l48, formed at `one y side with avr- Kforwardly extending bracket arm-49 to which are' attached the pivots/14 and 46. The pivotfor the pointer '48 iis indicated at 49". The lower :portion ofthe arm`49 projects forwardly with respeet to the upper'portion thereof whereby the pivot 46 is positioned in advance of the pivotgigz. ,The lowferpofrtion of the arm 49 carries a support 49 for the link 43. Assoltiiated with thepointer 48, for the purpose of shift-ing the saine,A is an angle shaped arm I51f-prf'irided with ani-opening 52 forme-d with a threaded wall. The arm 5l extends rearwardly fromtl'le upper end of the point er 48. Arranged rear\\ \'ardly of the pointer 48 is a quadrant shaped plate 53, in the bot- .torn of which, is n'iounted the *pivoty -49.`"

The pla'tei' has its forwardl face atfitsA top provided with gradnations ,54 whic'lrA associate with they pointer 48 to obtain lthe desiredr adjustment of the lcombined saw guide and vcarrier. when adjusting the llatter l to a verticallyinclined plane. The arm 5l' overlaps'thfe top ofthe plate and'carries a binding sCreW, having threaded engage ment with the wall of the opening and said'screw 55 Vabnts against the rear "face of `lever arm 56 is provided with a rearwardly directed angle'shapcd projection 57y which overlaps the forward portion 2O of the pla-te 17.7 The lever arm 5G at its forward end is provided with an opening A"58' "having a threaded waljl and whiclrengages a set screw 59 which when adjusted Vengages the portion 20 of -the plate 17 and-'maintains the lever arm 'i-n its adjusted position. When thecoinbinedsaw guide and carrier is angu- ,larly adjusted with respect to the sections 1,

' the plate 53 for maintaining. the pointer 48 2 and 3 of the table vtop the links, 42, 43 ,andl i the means 41 are bodily' carried therewith.

` The device' further includes ,an adjustable guide mechanism employed lin connection with .the combined v'savv-g'i1ide and carrier for the purpe of guiding-the 'latter in the position to Whichit Ahas been adjusted and also to iperrni't of the Sameto f'al'l away from "a-vertic'le plane. The said guide mechanism Icomprises a vpair of vertically disposed vbackrest extension -sllides,-between which the corn-` bined saw rguide and carrier passes. The vslides are manually shifted to the desired extentand'when so shiftedare locked from movement-.f1 The slides are indicated at `60,

61-and the inner end of each is beveled to conform tothe inclination of the portion 16 Vat `thelinner'end of a strip 9. The slides`60 and Gl, at their upper portions, are bentas at 62 to overlap the upper edges of the supports 4l `formed` on the body portion l of theV table top.' Each slide has lixed thereto aV clamping` screw 6i `which extends through the bent portion 62 thereofv and engages the -rear ii'ace ota support fl for Fixedlysecuring` the slide in set position. Thel slides are capable of being shifted outwardly and inwardly withv respect to the supports 4 for supporting the saw guide when `the latter is adjusted to h-old the sawin a `direction in angles in two directions at the rsame time, f

and further whereby the saw will be ixedly maintaincdin its various adjustments, therefore it is thought that the many advantages. of a miter box, in accordance with this mvention, can be readily understood, and although the preferred embodiment of. the invent-ion is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will :tall within the scope ot the invention as claimed.

lVhat I claim is:

1. In a miter box, a table provided at its rear with a pair ot lengthwise opposed,

spaced upright supports having oppositely,`

extending inclined inner ends, a pair lof lengthwise opposed, spaced independently adjustable, vertically disposed,` shiftable members positioned against the front and overhanging the top of said supports and providing means to permit a combined saw4 guide and carrier element to tilt lfrom a vertical plane and forsupporting said'element in tilted*position,v and meanscarried at the rear ot the 'overhanging part of each otsaid/ members lortixedly 'securing the ynir-amber in l set position.

2. A vmiter box' constructed in accordance..

with claiml v said supports and said members having" oppositely dlsposed bevelled inner correspondingy tothe bevelledinner endsA of said members.v

for a tiltable and diagonally'adjustable com# binedy saw bladeguide and carrier element, said mechanism including combinedsupportjing Vand rcoupling means for" said'element ,consisting ot a bracket having` itslower part' ot greater length than'its upper part,an`

ends. the'bevelled inner ends of the supports i upperlink for pivotal 'connection lwith said element and pivotally connectedto said up-v pe1f part, a lower link for pivotal vconnection with said'e'lement and pivotally connected yto said lower part, and a lsupport `for said lower link, said support'carried by said lower part outwardly `with respect4 to the pivot between lthe lower link and lower part.

4l. In a miter boX constructed in accord!` ance with claim'3,`said.lower link projecta y beyond the outer end of the upperlink.

In testimony whereof, I aiiix my signature hereto.
